Exscientia Business Update for Second Quarter and First Half 2024

Entered into definitive agreement to combine with Recursion to create a global technology-enabled drug discovery leader with end-to-end capabilities

Acquired full rights to GTAEXS617 (CDK7 inhibitor), with initial Phase I monotherapy data expected in 2H24

Launched AWS AI-powered platform to advance drug discovery

LSD1 and MALT1 inhibitor programmes continue to progress towards the clinic, on track for 2H24 IND/CTA submissions

Exscientia plc (Nasdaq: EXAI): Recent advancements in the Company’s pipeline, collaborations and operations, as well as financial results for the second quarter and first half 2024, are summarised below.

“Last week, we announced that Exscientia entered into a definitive agreement to combine with Recursion Pharmaceuticals,” said David Hallett, Ph.D., interim Chief Executive Officer and Chief Scientific Officer of Exscientia. “When we bring together our platforms at closing, our world class scientists and Exscientia’s best-in-class focused precision oncology internal pipeline with Recursion’s first-in-class focused pipeline, we believe we will be able to discover better drugs for patients faster and at a lower cost.”

“In the first half of 2024, we believe we have made important progress across our AI-powered pipeline and progress towards autonomous drug design as well as deepening our technology and pharma partnerships,” continued David Hallett, Ph.D. “We made the strategic decision to fully invest in our CDK7 inhibitor GTAEXS617 (‘617) by acquiring full rights to the programme, which we believe is highly differentiated and demonstrates the power of our design capabilities. We look forward to sharing topline data later this year.”

Key Business Updates

Transaction with Recursion

Second Quarter and First Half 2024 Financial Results

For the convenience of the reader, the Company has translated pound sterling amounts to U.S. dollars at the rate of £1.000 to $1.2640, which was the noon buying rate of the Federal Reserve Bank of New York on June 28, 2024.

Revenue: Revenue for the three and six months ended June 30, 2024 was $5.6 million and $12.3 million, compared to $3.8 million and $11.1 million for the three and six months ended June 30 2023. The increase in revenue year over year was primarily due to an increase in the number of active projects in the first half of 2024 relative to the prior period.

Research and development expenses (R&D): R&D expenses for the three and six months ended June 30, 2024 were $31.7 million and $61.5 million respectively, as compared to $41.7 million and $83.9 million for the same period ended June 30, 2023. The decrease in research and development expenses was primarily due to cost reductions relating to pipeline prioritisation activities implemented during the second half of 2023 and cost savings from operational efficiencies.

General and administrative expenses (G&A): G&A expenses for the three and six months ended June 30, 2024 were $21.2 million and $25.6 million, respectively, or 34% and 24% of total operating expenses. For the three months ended June 30, 2024, G&A expenses increased by $6.5 million compared to the prior year, primarily driven by current quarter severance and termination-related costs totalling $7.5m relating to the cost saving and efficiency measures announced in May 2024. For the six months ended June 30, 2024, G&A expenses decreased by $2.9 million compared to the prior year due to credits totalling $7.5 million relating to amounts recognised in February 2024 on the forfeiture of share options held by the Company’s prior CEO upon his exit from the Company.

Cash inflows: For the second quarter 2024, Exscientia received $1.4 million in cash inflows from its collaborations as compared to $0.7 million during the second quarter 2023.

Net operating cash flow and cash balance: For the three and six months ended June 30, 2024, net operating cash outflows were $45.8 million and $84.8 million respectively, in comparison to $52.2 million and $107.0 million for the three and six months ended June 30, 2023. Cash, cash equivalents and short-term bank deposits as of June 30, 2024 were $370.1 million, as compared to $458.9 million as of December 31, 2023 using the June 28, 2024 constant currency rate.
